Girder Tiedowns – LUGT series<br />
Truss & Rafter<br />
The LUGT series is an extremely adaptable tiedown for girder trusses and offers several installation options to<br />
accommodate different framing conditions. It is an ideal retrofit solution to reinforce truss connections to transfer<br />
high wind loads to supporting walls and can be used on either wood framed, concrete or CMU block walls.<br />
LUGT1 – is designed for wood framed walls.<br />
LUGTC2 – is designed for corner hip trusses on wood framed walls.<br />
LUGT2, LUGT3 & LUGT4 – are designed for wood frame, concrete or CMU block walls.<br />
Materials: See chart<br />
Finish: G90 galvanizing<br />
Codes: Factored resistances are derived from data submitted to various North American building code<br />
evaluators and are in accordance with CSA O86-09.<br />
<strong>Installation</strong>:<br />
• Use all specified fasteners. See Product <strong>Notes</strong>, page 10.<br />
• All nail holes must be filled with specified nails to achieve<br />
loads listed in the chart. Large holes are for concrete/<br />
masonry installations and do not need to be filled<br />
when used for girder-to-stud applications.<br />
• WS Wood Screws included with LUGT3 and LUGT4.<br />
• For concrete and masonry applications, a moisture<br />
barrier may be required, check local building code.<br />

1) Factored resistances have been increased 15% for short-term loads such as wind and earthquake; reduce for other load durations in accordance with the code.<br />
2) Factored resistances apply where roof pitch is between 3:12 and 8:12.<br />
3) Additional anchorage products to be designed by others.<br />
4) 1/4WB denotes a 1/4" x 3" Powers "Wedge Bolt" or equivalent installed in a predrilled hole. Refer to manufacturer's literature for further information.<br />
5) 3/8WB denotes a 3/8" x 5" Powers "Wedge Bolt" or equivalent installed in a predrilled hole. Refer to manufacturer's literature for further information.<br />
6) Fasteners must be installed in fully grouted and reinforced concrete masonry (f'm = 1500 psi) or reinforced concrete (f'c = 2500 psi).<br />
7) Minimum nail embedment shall be 8 nail diameters (typ).<br />
8) For proper installation, the number of studs must be equal-to or greater-than the number of roof truss plies.<br />
9) Wedge Bolts are not supplied with the LUGT2, LUGT3 or LUGT4.<br />
